All Terminals Open at Los Angeles International Airport

Los Angeles International Airport has reopened the terminal where a gunman killed a federal security agent and wounded at least two other officers.

Airport officials say Terminal 3 is completely open to passengers, one day after the deadly shooting. The suspected gunman is identified as 23-year-old Los Angeles resident Paul Ciancia.

Authorities are working to find a motive after the man opened fire at the airport with a semi-automatic rifle.

Officials say he was carrying a note saying he wanted to kill members of the Transportation Security Administration. They say the note indicated he had no interest in hurting "innocent people."

Police say the gunman shot his way past an airport security checkpoint before being wounded in a gunfight with authorities and apprehended. Witnesses say the suspect did not fire at people who said they were not TSA employees.

Evidence indicates the gunman acted alone.

Officials say the gunman had sent a text to a sibling suggesting he was prepared to die.

Authorities have not ruled out terrorism as a motive. Several other people were shot and wounded in the incident.

The slain employee was the first TSA officer killed in the line of duty in the 12-year history of the agency. The TSA, which screens airline passengers, was founded in response to the 9/11, 2001 terrorist attacks on the United States.
